Making my Own Power [1.10.2]

[NoVaGaming]

Im kind of new to coding so im not that good at java like i can create custom blocks and items and jsons but thats where im limited. I dont know how to make my own power so if one of you lovley people could teach me or link me to somwhere without using an API it would be much appriciated

Well, energy is simply an amount that goes up and down.

You'll need:

• Storage: how much something can possibly have
  
• I/O: How much can enter/leave a suitable storage
  
• Generator: A way to get this energy
  
• Transport: How to move this energy from point A to point B
  

 

I would recommend you create your "own API"; make Interfaces that handle each of these points separately (IEnergyStorage, IEnergyInput, IEnergyOutput etc), then create abstract classes that implement these classes, and then, finally create your proper classes, that extend the abstract class. It's a bit extra work, but leaves you with a clean workspace with easy-to-use classes.

Yea i just got so fing confused dude. I dont know much at all about java and i know your gonna say go learn but im trying to focus on modding are there any tutorials because i dont know how to code really well. I dont know most of the terms you just explaned

[imadnsn]

I dont know most of the terms you just explaned

 

if you mean

• Storage: how much something can possibly have
  
• I/O: How much can enter/leave a suitable storage
  
• Generator: A way to get this energy
  
• Transport: How to move this energy from point A to point B
  

 

then that's not java-related but explaining what you might want to do.

[NoVaGaming]

Yea but i dont know how to code those things or my own API

[NoVaGaming]

I just want somone who can teach me because im confused

[Draco18s]

You don't have the Java knowledge necessary to even have someone help you with this.

If somone just shows me the exect code i can just replicate it then learn it. I learn from people showing me

I would Google java tutorials, and learn how classes, inheritance, and interfaces work before trying to dive into complex minecraft modding. You seriously won't learn anything copying other people's code without knowledge of those things.

This forum is not about providing drop-in copy-paste solutions. This forum should help people understand why they are having a problem and how to solve it and why X and Y solves it.

Then they do not have to ask next time.

If you do not agree with this mentality then yes by all means, please get off this forum.

Dude im not learning anything if i go watch tutorials. I dont have time. i have school too you know?

Then honestly, you should probably forget it and focus on school. When you get older you might have a shot at learning how to write java/make mods.

 

*edit: And I didn't mean to WATCH tutorials. Video tutorials are kinda crap for writing code. You need a txt tutorial.

Dude i got cofh api but now all i need to make is a generator and im stuck. So basicly its not java needed now i need to find out how to use it in blocks

write code, post it, along with errors, ask for help. No one is going to just write the code for you, especially when you don't know basic java terms like interfaces.

[NoVaGaming]

Well theres no way im going to learn if there is no documentation

Well then can you teach me ive been trying this for years and i want to keep trying just please teach me yourself

Read all of this in its entirety: http://tutorials.jenkov.com/java/index.html

Oh thank you now were getting somewhere

[Matryoshika]

No documentation? Then what is this?

Or that?

Here, found a few more pieces: 1, 2, 3.

That's all random classes found in the... public GitHub repo. Don't come here and say there's no documentation. How would anyone have made anything using the CoFH API if there was no documentation?

[NoVaGaming]

Im trying to figure out how to use them with items and where in my block class

A class can extend a single other class. It can also implement several other Interfaces.

An Interface is very similar to a regular class, in some points:

• An interface can contain any number of methods.
  
• An interface is written in a file with a .java extension, with the name of the interface matching the name of the file.
  
• The byte code of an interface appears in a .class file.
  
• Interfaces appear in packages, and their corresponding bytecode file must be in a directory structure that matches the package name.
  

However, the key differences are:

• You cannot instantiate an interface.
  
• An interface does not contain any constructors.
  
• All of the methods in an interface are abstract.
  
• An interface cannot contain instance fields. The only fields that can appear in an interface must be declared both static and final.
  
• An interface is not extended by a class; it is implemented by a class.
  
• An interface can extend multiple interfaces.
  

 

To describe what an Interface is, in layman's terms: An interface provide methods that has to exist in whatever class implements it. If class MyCustomClass implements ICustomInterface, which has a method called myCustomMethod, then MyCustomClass must have a method in it with the same name, and same variables. However, that is all. An interface cannot be used to do anything, only make sure that the methods that actually do the stuff, exists in the class.

Interfaces create methods without any body. Just name & variables, like this:

static boolean hasEnergy(int energy);

It is up to the one creating the class to actually make the hasEnergy method return anything.

Yea so with CoFH Core How do i add those methods to my block

[Draco18s]

An interface cannot contain instance fields. The only fields that can appear in an interface must be declared both static and final.

 

In C# you can, but really all that means is that the interface is declaring an explicit getter/setter.  I know this because I did it not to long ago.

 

e.g.

public interface ISomeThing {
    public someField {
        get; set;
    }
}

 

But yes, you can't do that in Java.  You'd have to declare it as a

getField()

and

setField(v)

methods and supply the field itself in the implementation.

public class MyCustomClass extends SomeClass implements ICustomInterface, IOtherCustomInterface
